HIGH-EFFICIENCY POWER REFRIGERATING PLANT Russian patent published in 2001 - IPC

FIELD: power engineering, applicable for generation of mechanical or electric energy, as well as for production of refrigerant. SUBSTANCE: liquefied natural gas is fed from the tank through the regulating valve and fuel feed line to the gasifier, whence through the throttling valve - to the refrigerating chamber, cools down the cooling chamber interior, get heated with a rise of pressure. Then, in a vortex tube the gas is divided into two flows: the cold and warm ones, the cold flow line is directed again to the refrigerating chamber, and the warm flaw line through the heater runs to the turbine, where gas expansion makes it possible to obtain and additional power for the load. The Stirling engine exhaust gases through the exhaust gas line pass through the heater. With the aim of Stirling engine cooling provision is made for a cooling system with a cooler, in which heat exchange occurs with the environment (for example, atmospheric air) and the pump; the cooling system passes through the gasifier. EFFECT: enhanced efficiency of the direct cycle converter of the power refrigerating plant thus producing an additional power. 1 cl, 1 dwg
